2 It receives a current signal from a host and uses instrument air supply to create a metered pressure output signalto the pneumatic actuator. Movement of the actuator as it positions the process control valve is measured by theDVC6200 travel sensor as its primary feedback. The name plate is located on the bottom side of the DVC6200 mastermodule assembly and indicates the model name, individual product serial number, and any applicable third of this documentThis Specification is designed to be a technical reference for hart capable host application developers, systemintegrators and knowledgeable end-users.

3 It also provides functional specifications ( , commands, enumerationsand performance requirements) used during Field Device development, maintenance and testing. This documentassumes the reader is familiar with hart Protocol requirements and terminology. Additional product information isavailable in DVC6200 product literature, available from Emerson Process and definitionsARAlert RecordConfigurationVariablesVariables which represent nonvolatile values of manufacturing initialized data oruser specified configuration information. These variables cannot be enumerated viaCommand 54 and as such stand on their own with no associated units or range VariableMeasured variables that are exposed to hart and can be enumerated using Command there are variables whose ID is in the range of 0 to 13 and are associated with unitscodes, status, and range pre-defined set of values or Variable, a physical input to the Variable a logical point inside the Device , hard mapped to a given MV as the sourceof NV term that applies to diagnostic data packets.

Pressure sensors in the DVC6200 measure these pressure signals andpresent them as Device variablesHost interfaceThe input to the DVC6200 can either be two wire 4 to 20 mA current loop (in point to point mode) or 24 VDC (inmulti drop mode). This input is connected in the DVC6200 s terminal box on two terminals marked LOOP + and LOOP.

7 Refer to the DVC6200 Series quick start guide for connection CalibrationA pushbutton near the wiring terminals in the terminal box provides a quick means to autocalibrate the travel of theinstrument. The button must be pressed for 3 to 10 seconds. Autocalibration will move the valve through the fullrange of travel whether the Instrument Mode is In Service or Out of Service. However, if the Write Protection isProtected, this button will not be active. To abort, press the button again for 1 second. The calibration button isdisabled by Manual SupplementD103639X012 DVC6200 Digital Valve ControllerAugust 20145 Internal Jumpers And Switches (Optional)The input to the DVC6200 is determined by the Pt Pt/Multi Drop switch on the printed wiring DVC6200 also has a pair of optional Output terminals that can either function as a position transmitter or adiscrete switch.

8 Electrical configuration of the output circuit requires the proper setting of a DIP switch on theDVC6200 s printed wiring board. Additionally, the functional operation of the output circuit must be configured withthe user to the DVC6200 instruction manual for additional details on the settings of the selection +OUTPUT-X0430 WITH OPTIONAL I/O PACKAGEX0431 WITHOUT I/O PACKAGEPT-PT/MULTI-DROPSELECTIONX0432 DIP SWITCH FOR TRANSMITTER/SWITCHSELECTIONX0427PT-PT/MU LTI-DROPSELECTIONW rite ProtectionThere are two Write Protection states for the DVC6200: Not Protected or Protected.

9 Protected prevents configurationand calibration changes to the instrument. The default setting is Not Protected. Protection is controlled undersoftware control. Write Protection can be enabled remotely. However, to disable Write Protection to Not Protected,you must have physical access to the instrument. The procedure will require you to press a button inside the terminalbox when directed by the software as a security Manual SupplementD103639X012 DVC6200 Digital Valve ControllerAugust 20146 Dynamic VariablesFour Dynamic Variables are MeaningUnitsPVAnalog InputmA, %SV*Travel Setpoint%TV*PressurePSI, BAR, KPA, Kg/cm2FV*Travel%* User selectableThe SV, TV, and FV variables are user selectable via Command 51 to any of the following variables.
